Frydenberg 

When someone makes up claims for a future win without any backing, often leading to the complete opposite.

"A year ago Josh got up on TV and said we're back in the black, but now out debt is 4 times what it was? He did a Frydenberg on us!"

Frydenberged 

Verb, specific to Australia: To have a stable, profitable and successful business with many happy clients suddenly destroyed by a federal treasurer focused on his own political objectives and seeking to gain the approval of a biased ex-judge and his cronies.

I had over 500 happy clients but I got Frydenberged in 2021 and now I work the late shift at the Pizza shop on High Street.
We do make great pizza.
